Is Monday a holiday or is tuesday green beer day?

Hi,
It's not Monday nor Tuseday but Thursday.  Green beer day is celebrated always on the last Thursday just B4 the Spring break. 
Best regards,

Here is a short quote (from Wikipedia): "Green Beer Day is a holiday celebrated by students at Miami University in Oxford, Ohio. It is celebrated on the Thursday before Spring Break every March. The holiday begins at 5:30am when the bars open to serve green-colored beer, shots, and cocktails to waiting Miami students (The state of Ohio forbids bars from serving alcoholic beverages before 5:30 am.)"
